The mother of an Australian baby which miraculously survived a collision with a train is still recovering from the experience and becomes upset by footage of the accident, a report said Sunday.

The six-month-old boy, who has not been named, was strapped into a pram which rolled away from his mother and into the path of an oncoming train at Melbourne's Ashburton station on Thursday.

The train driver slammed on the brakes but was unable to avoid hitting the stroller which was pushed about 35 metres (yards) along the tracks before coming to a stop. The baby escaped with only a bump to the head.

The incident was captured by a surveillance camera and the video has been shown around the world, sparking the interest of US talkshow queen Oprah Winfrey whose producers have contacted Victoria Police to interview the mum.

The baby's father said his wife had seen the footage, which shows her slipping as she attempts to grab the pram as it rolls away and then almost getting hit by the train herself in a bid to save the baby.

"My wife has seen the footage, but every time she sees it she gets very upset," the 20-something man, who asked not to be identified, told Melbourne's Sunday Herald Sun.

"My wife is very stressed. We are all OK -- my wife and my baby are OK -- but we really just need some time to get over this."

Paramedics said the fact that the baby was properly strapped into the pram at the time of the accident probably saved his life.
